Full brims, mouse ears, with glue, without glue, higher bed temperature, lower bed temperature, flat base, concentric cutout base - whatever I try, I seem to be getting wank adhesion, major warping, and ultimately this shitshow.
Dry PLA, warm room, no draught, plate cleaned with IPA. I’m going to fucking punch this thing in its stupid fucking face.
Edit: Prevailing advice very much seems to be to bust out the Fairy liquid and give it a good scrub, so I’ll try that. It’s a Kobra Neo 2 so is auto-levelling, so I can’t piss around with any of that stuff (as far as I know). Another quick question while I think about it, does everyone always print onto the bed at ~60°C? Because Orca Slicer’s default for a textured PEI plate is 45°C, which seems mad. I think I tried it once and it was shite so turned it back up to 60.
I fucking love it! I have been there so many fucking times to the point of putting a hole in a wall. Best part is I’d give up walk away for a month or so then literally turn the stupid fuck on and press print and it would print just fine. I just use glass on one printer and carbon fiber on the other. I had pei once threw that shit right in the garbage. A good scuff with 80 grit sand paper on both and wash off with rubbing alcohol. I did have an issue once with a bent touch probe that would fuck my z offset so the first layer wouldn’t actualy be low enough.
